Journal ArticleDOI
Why biphenyl configuration still matters
TL;DR: In this article, the first circular extinction imaging microscope was proposed, which can detect circular dichroism in low-symmetry media, and also a new effect in crystal optics that they call anomalous circular extinction.
Journal ArticleDOI
Dislocation Generation by Microparticle Inclusions
Xiaodi Zhong,Alexander G. Shtukenberg,Mingzhu Liu,Isabel A. Olson,Marcus Weck,Michael D. Ward,Bart Kahr +6 more
TL;DR: In this article, the correspondence between the size and shape of inclusions and the probability of dislocation generation in solution-grown crystals has been studied, showing that inclusions are common sources of dislocations in solution grown crystals.
Journal ArticleDOI
Structure, Energetics, and Dynamics of Screw Dislocations in Even n-Alkane Crystals.
Isabel A. Olson,Alexander G. Shtukenberg,Gagik Hakobyan,Andrew L. Rohl,Paolo Raiteri,Michael D. Ward,Bart Kahr,Bart Kahr +7 more
TL;DR: Molecular dynamics was used to examine heterochiral dislocation pairs with Burgers vectors along n-hexane, n-octane, and n-decane crystals to suggest a pathway to understanding the mechanical properties and failure associated with elastic and plastic deformation in soft crystals.
Journal ArticleDOI
Timoshenko Bending and Eshelby Twisting Predicted in Molecular Nanocrystals
Chao Li,Alexander G. Shtukenberg,Damien J. Carter,Xiaoyan Cui,Isabel A. Olson,Andrew L. Rohl,Julian D. Gale,Paolo Raiteri,Bart Kahr +8 more
TL;DR: In this article, a force field is evaluated for the ability to predict mechanical distortions in nanocrystals, and an optimized force field based on AMBER parameters matches expectations for elastic and plastic distortions, despite the fact that these mechanical responses are far removed from the force field para...

Circular extinction contrast imaging microscope
Werner Kaminsky,Bart Kahr +1 more
TL;DR: In this paper, a tunable filter, a rotatable linear polarizer and a variable retarder are used to produce near perfect circular extinction (CE) images at each selected wavelength.
